Weekend traffic advisory for I-15 and 91

Plan your weekend travel accordingly. Part of the interchange connecting the Riverside 91-Freeway to Interstate 15 in Corona will be shut down this evening. Motorists should expect delays and plan to take alternate routes.

Crews will be working on the 91 freeway expansion project to modify connector ramps that allow motorists to transition from southbound and northbound I-15 to the westbound 91.

The connectors will be closed from 9 p.m. to 8 a.m. Sunday, according to the Riverside County Transportation Commission.

Detour signs will direct drivers beneath the interchange, bypassing the roadwork, and into the city of Corona, where they will be able to join the westbound 91 via McKinley Street. Traffic along the detour route will be slow.

Additional closures are planned at the interchange in the coming months, officials said.
